Study Notes
Cell Structure
- Plasma membrane: semi-permeable membrane that separates the cell from its environment
- Cytoplasm: jelly-like substance inside the cell membrane, where metabolic processes take place
- Nucleus: control center of the cell, contains genetic material (DNA)
- Mitochondria: energy-producing organelles, responsible for cellular respiration
- Endoplasmic reticulum: network of membranous tubules and cisternae, involved in protein synthesis and transport
- Ribosomes: small organelles, site of protein synthesis
- Lysosomes: membrane-bound sacs, contain digestive enzymes for breaking down and recycling cellular waste
- Golgi apparatus: complex of flattened sacs, involved in protein modification and secretion
Cell Functions
- Metabolism: conversion of energy and nutrients into usable forms
- Growth and development: increase in cell size and number, differentiation into specialized cells
- Response to stimuli: ability to react to changes in environment, e.g. light, temperature, touch
- Reproduction: creation of new cells through cell division (mitosis or meiosis)
- Cell signaling: communication between cells, through chemical signals (hormones, neurotransmitters)
Cell Types
- Prokaryotic cells: lack nucleus, typically small and simple, e.g. bacteria
- Eukaryotic cells: have nucleus, typically larger and more complex, e.g. plants, animals, fungi
- Stem cells: undifferentiated cells, capable of differentiating into various cell types
Cell Division
- Mitosis: division of somatic cells, results in two identical daughter cells
- Meiosis: division of reproductive cells, results in four non-identical daughter cells with half the number of chromosomes as the parent cell
Test your knowledge of cell structure, functions, types, and division. Learn about the components of a cell, cellular processes, and the different types of cells and cell division.
